I was assuming his application was home audio where he wouldn't be dealing with particularly long lengths of cable in which case a served shield or even no shield at all can work perfectly well.

I don't think you're getting the point. Foil/drain brings LESS symmetry to a symmetrical pair than, for example, braid and foil.

I want all the electronics and their connexions in a continuous Faraday cage. Therefore, I want a cable shield with low impedance connections to the enclosures that house the sending and receiving electronics. As was mentioned by Steve Eddy, for home electronics with short length cable runs, it probably doesn't matter that much, but I want perfection, so a <5mm balanced braided shield cable is what I yearn for.

It will be a challenge to solder it together in mini XLR, but with the help of a stereo microscope it can be done. Probably.

The star quad is a bee-atch I agree, even with normal XLR, but you'll be a better person for the effort. Plus the cable is more immune to magnetic fields than ordinary twisted pair.

Perfection? I think there's another word for that but I'll just bow out now.

Steve, that word probably got to do with approximately the part I am sitting on right now, with 'retentive' added.

I wasn't clear enough, as in my case I also need to design for large cable runs >25 meter to active speakers with classD amps and switched power supplies, so it is also a matter for EMR not radiating out.

Oh, please !!!
Look at the image.
Belden is a top professional cable manufacturer and know how to build cables for audio: the drain is OUTSIDE the foil, and the foil is not spiraled; They provide specs, just look at them.

I trust John C has some thought about lemo connectors.

About Belden 1023A, this cable is very good both for sap-in connectors, because both the conductors and the isolators are very solid, and for welding because isolators are high temperature resistant. That's all the difference between an 'audiophile' product and a real professional one, easy to set and weld, long lasting, and very good performance. But they don't look anything like spacial or exotic.
